[j-nsp] PCMCIA flash upgrade/config

[Craig Pierantozzi]

The pc card and LS-120 disk are used for recovery.  The 
internal compact flash and internal hard drive are used as primary 
and alternate boot devices. The M7i is a bit different since it does 
not have an internal flash drive.

Normally, the PC card is left out of the router and the
boot order is internal compact flash then internal hard drive.  
If the PC card is present, the router boots from it but the 
functionality of the router is impaired.  It's really for
disaster recovery where you boot from the removable media
then reinstall JunOS onto the primary boot device.
